When I launch Resolve it starts with "Welcome to Davinci Resolve 14" setup screen with options "Welcome tour" and "What's new?". I did welcome tour and I did "Quick setup" after which Resolve displayed message "You're all set We hope you enjoy Davinci Resolve 14!". Upon pressing Start button, Resolve opened Untitled Project.

All good for first time, but I did expect that when I play with Resolve, save project, close the Resolve and open it again, I would be immediately presented with Project screen. This is not happening, every time I open Resolve it presents the same Welcome screen with the same option to do tour and same option to do quick setup. To get to project screen I need to skip tour, skip setup and than click home button from Untitled Project which Resolve always opens for me as a default.

It seems that Resolve does not remember that I already did the tour and quick setup.

How can I setup Resolve so on opening it goes directly to Project screen?

I'm hopefully answering my own question in case it helps anyone else here. I was having trouble with the initial "tour" and "Setup" screens coming up each time I started Davinci Resolve, just like Miroslaw.

Yesterday I just happened to go into Preferences and change the Storage Locations to add another drive. After that, Resolve stopped asking if I wanted a tour, or displaying the setup screen. I have no idea if fiddling with Preferences is why it stopped, or if it was coincidence, but it might be worth a try.
